这些行显示与对npm存储库的请求有关。

最后它说：org.artifactory.storage.StorageException - Failed to update the unique indices table，由org.postgresql.util.PsqlException: FATAL: sorry,too many clients already引起。
然后，CI作业退出
npm ERR! 500 Internal Server Error - GET https://artifactory.company.com/artifactory/api/npm/npm/some-package-name
有人可以帮忙吗？
解决方法
此错误表明PostgreSQL数据库已用完数据库连接。 我建议您根据可用的here公式来增加数据库侧允许的数据库连接。
